ADJUSTABLE PUMP-BRACIE To all whom it may concern Be it known that I, LOREN H. RAMBO, a citizen of the United States, residing near Maquon, in the county of Knox and State of Illinois, have invented a new and useful Adjustable Pump-Brace, of which the following is a specification.

lWIy invention relates to devices whereby pumps and pump-stocks or tubes may be held from sidewise movement in wells, cisterns, etc, and it consists, substantially, in

the improvements hereinafter described.

The principalobject of the invention is to provide a brace and pump-clamp which may with facility and ease be attached to a pump or its stock and which may be adjusted to cause it to bind against or frictionally contact walls of wells of different diameters.

Minor objects will be in part obvious and in part specifically pointed out.

By way of example a practical and preferred embodiment of my invention is illustrated in the accompanying drawings, in which:

Figure 1 is a perspective of my improve ments, shown as in operative position in a well, a portion of the wall of which is also shown; Fig. 2, a side elevation, slightly modified from the form shown in Fig. l, of the base-plate; Fig. 3, an enlarged top plan detail of one of the staples, shown as secured to the base-plate; Fig. 1, a top plan detail of one of the friction or pressure heads and one of the spreader-screws connected therewith; and Fig. 5, an end detail of one of said heads. 1

Coming now to a detailed description of said drawings, and referring to each element, and, where necessary, to each part thereof, by a distinguishing reference numeral, uniformly employed, 2 designates a base-plate provided at each end with a pair of projections-3 arranged at right angles to its body portion, the pairs being preferably arranged one on each face of the plate, as shown in Fig. 1; however, if desired all of said projections may extend in the same direction, as shown in Fig. 2. Each pair of projections is preferably provided with registering threaded apertures for the engagement of a spreader-bolt or screw 1 having an enlarged head 5 and angular shank 6,

the latter provided with a transverse open- Specification of Letters Patent. Patented Apr. 4:, 1916. l

provided with an opening in which the.

shank of the bolt 1 is loosely seated.

11 indicates a clamping-staple engaging a pair of the apertures 8, embracing a wooden pump-stock or tube 12, andlocked thereon by nuts 13.

14's indicates a clamping-'stapleengaging pair of apertures 8, embracing a metallic pump-stock or tube 15, and locked thereon by nuts 16. I 7 17, 17 indicates portions of the brick wall ofawelL; f The pump having'been placed in the well and the proper staple, ll'orv 14: as the case maybe, having been removed from the baseplate, the other parts of the brace may be positioned inv a well in substantially the same position shown in Fig. 1, but of course, loosely. The pump is then placed where desired and the staple positioned to embrace it, the limbs thereof passed through suitable ones of the holes 8 andthe nuts threaded tightly thereon to clamp and hold the stock and pump from movement relatively to said plate. 'The screws 4 are then turned in such manner as to force the pressure heads into frictional contact with the wall 17. The operation (or a reverse one) may be performed by engaging the angular portion 6 of either or both screws by a wrench or a nail or the like may be inserted in the opening 7 and used as a lever. All the pro jections being threaded, each pair will act as lock-nuts for the coacting screw 4.

The apertures 8 are placed at equal distances from each other, and the legs of the staple 14: are made to fit adjacent ones thereof, while the legs of the staple 11 fit apertures counted as thirds. Should a double-tube pump be used it will be evident that it will be better to employ both staples, the size and character of which may of course be altered to suit. The apertures 8 running substantially to the ends of the plate 2 makes it possible to place the pump at practically any desired position in the well. When the device is used in cisterns the heads 9 are so placed as to bear against the concave face of the curb. Inasmuch as the device is constantly exposed to moisture and liable to rust, I prefer that it be galvanized.

In order to insert the ends of the screws through the apertures in the pressure-head trusses said heads are made sufliciently small to pass therethrough, and may then be flattened and thus enlarged to such extent as to prevent their escape.

Having thus described the nature of my invention I claim as new the following, to-wit:

1. A pump-brace comprising a base-plate provided near each of its ends with a pair of projections arranged at right angles thereto, each of said projections provided with a threaded aperture and said plate with a series of apertures, a staple adapted for engagement with selective apertures in the plate, means for securing the staple to the plate, screws each engaging the apertures of a pair of said projections, and arciform pressure-heads each having a truss projection provided with an aperture J through which the stem of said screw loosely passes, the head of each screw adapted to bear against the concave face of the adjacent pressure-head. v

2. A pump-brace comprising a base-plate, screw-bolts engaged one with each end portion thereof, each screw-bolt having a stem and a head, pressure-heads having each a truss projection provided with an aperture in which the stem of the screw-bolt is loosely seated, and means securable to sald plate for engaging a pump-stock.

3. A pump-brace comprising a base-plate,

4. A pump-brace comprising a base-plate" provided near each of its ends with a pair of projections arranged at right angles thereto, each of said projections provided with a threaded aperture and said plate with a series of apertures, a staple adapted for engagements with selective apertures in the plate, means for removably securing the staple to the plate, screws each engaging the apertures of a pairof said projections, and arciform pressure heads having each a truss projection provided With an aperture through which the stem of said screw loosely passes, the head of each screw adapted to bear against'the concave face of the adjacent pressure-head. I In testimony whereof I hereto affix my signature this 22nd day of May, 1915, at V Galesburg, Knox county, Illinois.
